Zipper Binders  (34 Products)
Zipper binders are typically covered in polyester to keep everything inside safe and dry. They hold paper on the included rings, and hold pencils, pens, tablets, and other supplies snugly inside inner and outer pockets. Choose a binder that is large enough to hold the required amount of paper and has all the extra needed useful features. Read More

Zipper binder features

Besides the polyester cover with integrated zipper, these 3-ring zipper binders have other features. Some include pages with tabs to keep papers organized. Select models have removable expanding accordion file folders to store pages that are not punched for rings. This lets users file documents according to subject or customer name. Tablet binder pockets fit devices snugly so they don’t bounce around when carried. Inside mesh pockets allow users to hold supplies and see them without digging around in the pocket. Clear sheet protectors keep paper from getting dirty or wet, but users can still see the writing without removing it from the protector. Carry the binder with an included handle or shoulder strap that helps bear some of the weight.

3-ring zipper binder ring types

There are three rings in the center of the binder that match up with the punched holes on papers. These binders usually come with one of two types of rings. Traditional round rings let users flip pages from one side of the folder to the other so they lie flat on either side. D-rings have one flat edge while the rest of the ring is round. The flat side means these rings hold more paper than on a similar-size round ring.

Zipper binder ring sizes

The size and shape of the rings in a binder determines how much paper it can hold. D-rings can hold around 25 percent more paper than round rings. This is the average number of regular printer or multipurpose paper sheets 3-ring binders hold:

  • 1 to 1.5-inch rings can hold up to 400 pages
  • 2-inch ring binders can hold up to 500 pages
  • 3-inch zipper binders can hold up to 700 pages
  • 4-inch rings can hold up to 1,000 pages
